An SQL statement to get a subscription. Special formatting characters may be used. Special variable %2 contains a tenant id, %3 contains object's id and %4 contains object's name. If GetSubscriptionQuery is defined as an empty string, then the query will not be executed.

%0 and %1 are undefined.

GetSubscriptionQuery defaults to:

SELECT * FROM SUBSCRIPTIONS WHERE tenant_id=%2 AND (name=%4 OR id=%3)
